How to install

  1. On your phone, tap Download for Android above. If Chrome asks whether to keep the file, tap Download.
  2. Tap Open when the download finishes, or open it from your phone's Files or Downloads app.
  3. The first time, Android asks to allow installs from this source. Tap Settings, turn on Allow from this source, then go back.
  4. Tap Install, then Open. You will find ELDT Systems with your other apps.
Why does Android warn me? Android shows this warning for any app that does not come from the Play Store. The app is signed by ELDT.Courses. You can check the file with the SHA-256 number above. It runs eldt.systems in Google Chrome, so it needs Chrome on the phone (nearly every Android phone has it).

iPhone and iPad

On iPhone and iPad, you add the app to your Home Screen from Safari. It opens full screen with its own icon, just like an app from the App Store.

  1. Open Safari and go to eldt.systems/start.html.
  2. Type your school's web name and tap Open (or tap the link in your invitation email).
  3. Tap the Share button at the bottom (top right on iPad).
  4. Scroll down and tap Add to Home Screen, then Add.
  5. Open ELDT Systems from your Home Screen and sign in.

Don't see "Add to Home Screen"? Make sure you are in Safari, not another app's built-in browser. On iOS 26 and newer, tap the three dots (•••) first, then Share.

Computer

Nothing to download. Go to eldt.systems/start.html in Chrome, Edge, Safari or Firefox and open your school. In Chrome or Edge, you can also click the install icon at the right end of the address bar to give it its own window and a desktop icon.

Updates

New features reach you on their own. The app runs ELDT Systems directly, so every improvement we make shows up the next time you open it, on every phone.

Android app updates are rare. They are only needed when the app's own shell changes. When one is ready, the app tells you when it opens: tap Download the update, then Install. Your records and sign-in stay as they are.
